Exclamation No Ac!!! So Hot!!

Hi, the last owner of my TII routed the Climate Controller into the glove box.

when i relocated the logicon, the 13 pin wire connector had same color wiring, 3 yellow and 2 brown wires and i do not know which ones are right

now the blower motor doesn't turn on. when i press the AC button and move the fan switch to on position, i hear the compressor turning on but nothing comes out of vents!!! SOMEONE HELP! HEAT WAVE COMMING SOON!

Have you checked the FSM wiring diagrams?

all the wires coming from the logicon are different, so I am not sure what you mean by the " 3 yellow and 2 brown wires".

There are no solid brown or solid yellow wires coming from the stock system. There is a brown/red and a brown/yellow, but no solid brown wires.

Ok i've found out what happened
the guy used new wires and solded them on, so now i have all the wires connected back to its original color coding and connection. but the blower still doesn't turn on. When i move the switch to the right (MAX) position, i hear a click from the passanger side, that is where the blower motor is located.

when i turn on my parking lamps, the orange lights of the logicons light up, even the temperature control side (left side) but the ON OFF switch side doesn't light up, i checked the blub and it is not burnt. what else can i check?

The only lights that car controlled by the parking lights in the Logicons are the two bulbs that light the icons (top row, and sliders row), and the two LEDs in the sliders.

So you should still get the mode indicator lights (the lights above each switch) to light when that switch is turned on.

If they do not, then I suspect the logicon is not wired correctly, as even if there were problems in the display, at least one of the indicator lights should still work.

As for the blower, there are two possibilities.

One, that the blower resistor is bad on the blower.

or

Two that the blower amp (the black box mounted on the back of the logicon) is disconnected or damaged.

and there is no On/Off switch on a Logicon, so I am not usre exactly what you mean by that.

by the on/off switch i mean the slider

the mode indicator lights all work, the re-circulate light and AC light works as well

the temperature slider works as well...

so the only thing is i don't have anything blowing out of the vents

i got the same problem man, all the things work fine except the damn compresor doesnt engage, i replaced the das and after that, it all went down hill mark, if you read this, i am going to order that logicon in blue lighs, really hot. its funny b/c it all worked fine, i saw that the cable that snakes behind the dash was loose and i had to remove the top vents alnog with the metal cover and getting under the steering wheel you get a clear nice view to stick your arm in there. after i hooked it up, all things work except the a/c maybe the compressor, i dont know, but the logicon doesnt even light up the a/c light

See you must be clear.

Is no cold air coming out (as in the A/C is not working) or is no air coming out (as in the blower is not working)?

If it is no air, see my above responses.

If it is no A/C then that is a whole different bugger.

no air is coming out of the vents. when i slide the switch to MAX position, there is a click around the passanger seat area (where blower motor is located) but no air comes out of ANY vents.

the AC works fine, assuming that air will blow out...
